these ESAS items < 7, there exists <3% false positive risk. An expanded 5-item model added Lack of Appetite, Pain, and bone marrow primary site; this increased sensitivity and accuracy at the expense of specificity and PPV. We consider this less clinically functional than the two-item screen. Conclusion This is one of the first reports of PRO data screening for a clinical sign: in this case, anemia. Predicting freedom from anemia is feasible using 2 ESAS survey responses: if both Tiredness and Shortness of Breath are below 7. This will potentially aid clinical decision making for cancer patients in outpatient settings. PO-1290 100% peer review in radiation oncology. Is it feasible? E. Martin 1 , F.J.

Our purpose is to analyze peer review process at our institution. Material and Methods Based on our group peer review process, we recollected some data to quantify the rate of plan changes, time and resources needed for this process. We prospectively collected the data on cases presented in our daily institutional peer review conference attended by physicians, resident physicians and physicists. Items such as time to present per case, type of patient (adult or pediatric), treatment intent, dose, technique, disease location and receipt of previous radiation were gathered. Results Over a period of 4 weeks 148 cases were reviewed (Table 1). Median of attendants was 6 physicians, 3 in-trainning- physicians and 1 physicist. Median time per session was 38 (4-72) minutes. 60.1% of cases were presented in 0-4 minutes, 31.7% in 5-9 minutes and 8.1% in ≥10 minutes.79.1% of cases were accepted without changes, 11.4% with minor changes, 6% with major changes and 3.3% were rejected with indication of new presentation. Most frequent reason of change was contouring corrections.

Conclusion Everyday group consensus peer review is an efficient manner to recollect clinical and technical data of cases presented to ensure quality radiation care before initiation of treatment as well as ensuring department quality in a feedback team environment. This model is feasible within the normal operating of every Radiation Oncology Department. PO-1291 Management of pain in Radiotherapy Departments: preliminary results of an observational study C.M.

Pio da Pietralcina, Casa Sollievo della Sofferenza, San Giovanni Rotondo, Italy Purpose or Objective this is an ongoing observational prospective trial to evaluate the adequacy of analgesics prescriptions in Radiotherapy (RT) Departments (Dept), using the Pain Management Index (PMI). In this preliminary analysis we evaluated the correlation of PMI with intensity of pain and with some possible predictive factors. Material and Methods
